We've had water rationing for a couple years now and we are well below what we are allowed to use. I've lost a couple roses but that was partly due to my laziness in watering them. I did lose some daylilies and that was not my fault. They are on the lawn sprinkler cycle, which is where the rationing comes in, which apparently wasn't enough for them. The #$#@% vinca still goes like gangbusters. It apparently has suffocated some of my irises and amaryllis and it has started to get out of the flower bed and into the lawn. I pointed this out to DH since he's the lawn person, but it didn't seem to faze him much. Vinca survives in the wild here so even if we had to stop watering everything, we would still have vinca. Thrills.
